4 Logging up to 10 broadband parametersand 3 spectral parameters * . For more information, please refer to the relevant Product data sheet. Type 2270 only. Applications and Hardware Introduction Types 2250 and 2270 have generous hardware and software specifications. They deliver an extremely flexible instrument that can cover your current and future measurement and analysis needs from the traditional uses in assessing environmental and workplace noise to industrial quality control and development. These analyzers offer a technological platform for performing measurement applications in a compact and robust Hand-held instrument. This data sheet describes different combinations of software modules (applications) available for Type 2250. and Type 2270. All instruments come with the Sound Level Meter Software BZ-7222 enabled.

5 This makes them modern Class 1 Sound Level Meters (SLMs) and fulfill the requirements of the latest standard, IEC 61672 1, as well as earlier standards (see the specifications section for detailed compliance information). Even in their most basic configuration, these analyzers are delivered with a number of pre- defined measurement and display setups tailored to suit specific requirements. Optional Applications Additional applications that can be used in any combination can be purchased when needed and are delivered as easily installed licenses. Your Hand-held Analyzer investment is securely protected because when your need for measurements and analyses expands, these analyzers can accommodate your needs. Br el & Kj r is committed to maintaining an ever-growing range of applications on these platforms.

6 The optional applications described in this data sheet are: Frequency Analysis Software BZ-7223 analyse in real-time the 1/1- and 1/3-octave filter bands over a wide frequency range with a dynamic range from the noise floor in each individual band to 140 dB. Logging Software BZ-7224 freely select parameters to log at periods from 1 s to 24 h. Running together with SLM Software, all broadband parameters can be logged. If Frequency Analysis Software is also enabled, spectra can be logged at the same rates. Logging (or noise profiling) is used to develop time histories for use in environmental noise as well as workplace noise assessment Enhanced Logging Software BZ-7225 continuously monitor and log periodic reports in addition to the features of Logging Software. Parameters such as Ldn and Lden are calculated Signal Recording Option BZ-7226 attach actual samples of the measured signal to your measurements.

7 This option works with all other applications. The recording uses the measurement transducer, while voice annotations (standard) use a separate commentary microphone Tone Assessment Option BZ-7231 identify any 1/3-octave bands with audible tones above a set limit Information regarding the following applications can be found in their respective Product data sheets: Reverberation Time Software BZ-7227 start a basic measurement by clapping your hands. The traffic light' shows measurement status at a glance, and the resulting reververation time (RT) spectrum is shown as well as the average RT for the room. For assessing the acoustic quality of auditoria, halls, public spaces and workplaces. ( Product data BP 2152). Building Acoustics Software BZ-7228 and Dual-channel Building Acoustics Software BZ-7229.

8 Assess sound insulation in buildings and of building elements. Airborne as well as impact sound insulation can be measured, and final results shown on the spot to international (ISO) and 12 national standards. The required sound sources and PC reporting software are available, as well as complete building acoustics systems. ( Product data BP 2190). FFT Analysis Software BZ-7230 analyse frequency using the Fast Fourier Transform (FFT) algorithm, the tool of choice for measurement and diagnostics of machinery noise and vibration. The frequency profile' of a machine is its fingerprint, revealing sources of noise and vibration and their paths to the measurement position. Useful in Product development, troubleshooting, quality control and environmental noise measurements.

9 With Tone Assessment Option BZ-7231, FFT Analysis offers objective indication of tonal noise audibility and annoyance ( Product data BP 2183). Sound Intensity Software BZ-7233 (Type 2270 only) make sound intensity measurements from beginning to end. A single user can make complete intensity measurements for total sound power and noise source location. You can use the built-in camera to take a photo to aid in probe placement during measurment and for use as a background for a map of the results ( Product data BP 2341). Long-term and Continuous Noise Monitoring For long-term and continuous noise monitoring, Br el & Kj r offers a wide range of Noise Monitoring Terminal (NMT) and Noise Sentinel solutions that will meet and evolve with your needs. For more information, please consult Product data BP 2379 for NMT solutions and Product data BP 2389 for Noise Sentinel solutions.

10 2. Post-processing Software Measurement Partner Suite BZ-5503 is the next step in evolution from Utility Software BZ-5503, and its standard configuration is included with your Hand-held Analyzer . This configuration provides data archive, preview and export capabilities as well as software maintenance and remote online display. In addition to the free, standard configuration mentioned above, valuable data analysis and post-processing functionalities are now available in a growing suite of optional applications. Measurement Partner Suite offers these applications on a subscription basis: Only pay for what you need, when you need it. For more information on Measurement Partner Suite BZ-5503, please consult Product data BP 2430. Additional post-processing applications (available separately) include: Noise Explorer Type 7815 for data viewing and archiving Evaluator Type 7820 for advanced environmental noise assessment Protector Type 7825 for workplace noise assessment Qualifier Type 7830 for building acoustic measurement analysis Connectivity Fig.
